The Shield has been a dominant faction with just three members, but there are a number of candidates that could easily add to their numbers.

There are a number of candidates who would fit perfectly as the fourth member of The Shield

The Shield were one of the most dominant factions in WWE history from the moment the trio debuted at Survivor Series back in 2012, until their untimely demise in June 2014.

Over the past three years, the WWE Universe has waited for Seth Rollins, Roman Reigns and Dean Ambrose to be back on the same page so that a reunion could take place.

Finally, this happened on the October 09, 2017, episode of Monday Night Raw as the trio were inserted into a handicap Tables, Ladders And Chairs match at TLC against The Miz, Cesaro, Sheamus and Braun Strowman.

The Miz has found a fourth member for his team in the form of The Monster Among Men, but who would be a perfect fit for The Shield if they needed a fourth member in the future?

#5 CM Punk

Punk and The Shield had a fantastic feud back in 2013

CM Punk walked away from WWE back in 2014 after what was a fantastic feud with The Shield that saw him come out on top in a 3-on-1 handicap match at TLC back in 2013.

And lest we forget, the Hounds of Justice were originally supposed to serve as Punk's bodyguards during his run as WWE Champion in 2012.

It is unknown if the Chicago native will ever return to WWE, but if he did, it would make sense for him to join the group that hands out their own brand of justice since he has his own fair share of problems with many people in WWE right now.

Punk would have been a perfect addition to The Shield back in 2014, and the same can be said for "The Straight Edge" Superstar right now.
